[简单用法举例](https://developer.ibm.com/technologies/systems/articles/au-googletestingframework/)

#include "gtest/gtest.h"

double square‑root (double num) { 
    if (num < 0.0) { 
        std::cerr << "Error: Negative Input\n";
        exit(‑1);
    }
    // Code for 0 and +ve numbers follow

}

TEST (SquareRootTest, ZeroAndNegativeNos) { 
    ASSERT_EQ (0.0, square‑root (0.0));
    ASSERT_EXIT (square‑root (‑22.0), ::testing::ExitedWithCode(‑1), "Error: 
Negative Input");
}

int main(int argc, char ∗∗argv) {
  ::testing::InitGoogleTest(&argc, argv);
  return RUN_ALL_TESTS();
}
